[0002] With the development of the times and economic progress, the technology of construction has also been developed accordingly. The key means to improve construction and technology is to put various large-scale construction equipment into the construction of buildings. The use of these large-scale equipment has enabled the land and construction area of urban construction to be well controlled and reduced.

[0003] However, current small cranes all lift objects directly through hooks. Due to the lack of stable support for materials at high altitudes, the lifted materials are easily caused to swing in the air, especially when there is a sudden wind or other external force during the lifting process, which can easily cause large swings. Large swings can easily cause objects to fall from high altitudes, not only causing property losses, but also when the objects swing, the drag force of the lifting wire rope may cause the crane to be unevenly stressed and tilted due to uneven force, and in serious cases, it may cause injuries to on-site operators. Summary of the Invention

The two support blocks are respectively slidably connected to the inside of the two sliding rods, and the two moving blocks are driven to move by the rotation of the two trapezoidal screw rods, thereby driving the two sliding rods to move on both sides of the top frame.

[0009] Preferably, multiple support arms are fixedly connected on both sides of the top frame, multiple support arms are hinged at the bottom ends of each support arm, a stop block is formed at the bottom of each stop arm, and multiple card blocks are fixedly connected on both sides of the top of the base plate, and the multiple block blocks correspond to the multiple card blocks respectively.

[0010] Preferably, multiple tops of the support arms are fixedly connected to hydraulic cylinders, multiple output ends of the hydraulic cylinders are fixedly connected to tooth plates, multiple bottom ends of the support arms are rotatably connected to support shafts, multiple outer sides of the support shafts are fixedly connected to gears, multiple tooth plates are respectively meshed with multiple gears, and multiple gears are respectively arranged inside the support arms. The tooth plates are driven to move by the hydraulic cylinders, so that the tooth plates drive the gears to rotate, thereby driving the barrier arms to swing.

[0011] Preferably, multiple barrier arms are fixedly connected to both sides of the bottom ends with cylinders, multiple cylinders are slidably connected with positioning pins, multiple positioning pins correspond to multiple clamping blocks respectively, and multiple clamping blocks are provided with positioning holes, which are conducive to clamping the positioning pins and the clamping blocks to position the cylinders.

[0015] Compared with the prior art, the present invention has the following beneficial effects: 1. The present application enables multiple hydraulic cylinders to drive multiple tooth plates to move, and the multiple tooth plates drive multiple gears to rotate when moving, and the multiple gears drive multiple support shafts to rotate, so that the multiple support shafts drive multiple block arms to swing, and the multiple block arms swing downward, so that the multiple block arms and block blocks fit with the multiple blocks, and the multiple block arms drive the multiple cylinders to correspond to the multiple blocks, so that the inclined surface of the positioning pins just fits with the blocks, so that the multiple positioning pins shrink toward the inside of the cylinders, and when the multiple positioning pins shrink toward the inside of the cylinders, the multiple positioning pins are engaged with the multiple blocks, thereby positioning the cylinders, to fix the multiple block arms and the multiple blocks, so that the multiple block arms support and protect both sides of the steel pipe to prevent the steel pipe from slipping from both sides.

[0016] 2. When the two sliding rods of the present invention move, they drive the two side frames and the fixed frame to move, so as to adjust the spacing between the two fixed frames, protect the two ends of the steel pipe, and prevent the steel pipe from sliding to the two ends. The forward and reverse motors at both ends are started, so that the two forward and reverse motors drive the rotating sleeves to rotate when starting. When the two rotating sleeves rotate, the guide blocks are limited by the guide grooves, thereby driving the threaded rod to rotate. When the threaded rod rotates, the threaded rod is limited by the threaded sleeve, so that the threaded rod descends when it rotates, and the splint is driven to descend when the threaded rod descends. When the splint descends, the slide rail is driven to descend, so that the slide rail is lowered inside the fixed frame, so that the slide rail limits and clamps the two ends of the steel pipe, and fixes the steel pipe.

[0017] 3. This application causes the fixed frame to drive the two sliders downward, which in turn drives the axle pin and ring sleeve downward, which in turn drives the piston sleeve and hinge plate to deflect. When the piston sleeve deflects, it drives the piston plate and piston rod to deflect, which in turn drives the baffle plate downward, which in turn drives the baffle plate to push the positioning plate downward, so that the positioning plate contacts the top of the steel pipe. After the multiple positioning plates are in contact with the steel pipe, the positioning plates are deflected according to the contact surface with the steel pipe. When the positioning plates deflect, the positioning plates push the connecting rod to move, which drives the slide plate to slide outside the limit spring. The slide plate pushes the limit spring to compress, and the positioning plates, supported by the limit spring, are in contact with the positioning plates. This prevents the pipe from shaking during lifting. The contact of the positioning plates ensures the stability of the steel pipe during lifting. At the same time, the limit spring pushes the slide plate to slide outside the limit rod, further enhancing the fixing effect on the steel pipe. The operation of the entire lifting equipment, through precise mechanical linkage and limit control, achieves accurate control and safe protection of steel pipes. In addition, ensuring the safety of operators and equipment makes steel pipe lifting operations in high-rise building construction more efficient and safer. BRIEF DESCRIPTION OF THE DRAWINGS
